I notice in the scenario editor that you can't edit a saved game... it this something that will be fixed in the patch?
It is one thing to restart a random map game until you find an location and enviroment with plenty of resources... then you finally locate an AI CIV empire that is struggling to thrive in a sea of tundra and jungle... it would be good to play god and mix the terrain up a bit.
If Firaxis can't fix this.. then they better improve the map generation model... Jungles, mountains and tundra is applied just too sparsely.
I have to say the CTP2 editor was great in this respect!
